Hx750i psu 24pin no power output

[Clevis60]

I bought a the hx750i psu for my pic build about a year ago and it suddenly broke, I was berry confused because all the peri freaks were working but the pc was black screen. I took it apart to see if it could be fixed as it was over warranty. I can find nothing wrong nothing bulging everything good as far as I can see. Dose anyone have any ideas becuase it cose me a lot of money.

Thanks
